8400 Montana, .270 Win

Temp 75 degrees

WW brass, 150NP, CCI 250 primer, RL26
over a ProChrony

3 @ 59.0 = 3010
3 @ 60.0 = 3035
2 @ 61.0 = 3070

I had no pressure signs until 61 at which I noted primers had flattened. I was very pleased with the gains. Accuracy testing wasn't really achievable with the gusty winds but I was well within minute of elk. I'm going to work on it some more but for me this was a really good move. I am very pleased.

For reference I fired one cartridge with the same general setup using 7828ssc and got 2920 for a reading on the crony.
